Principles used in the finite element modeling and boundary element modeling methods are explained in this paper. These methods are useful to corrosion engineers in analyzing corrosion cell current distributions which are important in galvanic corrosion and cathodic protection. The paper begins with a description of how the current distribution phenomenon is represented by mathematical equations and how these equations can be solved using numerical calculations. A one dimensional corrosion cell is used to demonstrate the methods. Later, the procedures used in the numerical modeling methods are described. A comparison of the two methods is given in the discussion section. Factors affecting the accuracy of these methods are discussed. Suggestions are given to corrosion engineers who are interested in using numerical modeling to analyze their corrosion problems.
